What is a 12-Core SC Fiber Optic Patch Cord?
The 12-core SC fiber optic patch cord consolidates 12 individual fibers into one cable, simplifying high-density fiber management in data centers and telecom environments. It features SC fiber optic connectors with UPC polishing on one end and APC polishing on the other, enabling direct bridging between different interface types without conversion adapters. By replacing multiple simplex or duplex patch cords, this 12-fiber SC jumper cable significantly reduces rack clutter and cable tray fill.
Available in Singlemode OS2 (9/125µm, G.657.A1) and Multimode OM1–OM5 (50/125 & 62.5/125µm), this SC UPC to APC hybrid patch cord supports network speeds from 1G to 400G Ethernet. It is a practical solution for cross-connecting ODF frames, PLC splitter connections, or streamlining fiber distribution in GPON central offices and data center distribution terminals.

Connectivity Solutions
Central Office: OLT → ODF
Connect the APC end into the GPON/XGS-PON OLT (which requires low back-reflection) and the UPC end into the ODF patch panel. One 12-core SC fiber patch cable replaces a dozen individual SC singlemode fiber optic patch cords, cutting installation time and cable tray fill by up to 80%. Singlemode OS2 supports transmission distances up to 20 km at 1310/1550 nm.
Data Center: Patch Panel Cross-Connect
Deploy high-density SC cross-connects between MDA and EDA distribution areas. A single 12-fiber SC cable pull delivers 12 parallel links for leaf-spine or fat-tree topologies. Use OM3/OM4 multimode for 10G/25G/40G/100G short-reach interconnects.
Features
Tight-Buffered 12-Fiber Cable
The tight-buffered cable structure protects all 12 fiber cores and extends the useful life of the SC fiber patch cable. Aramid yarn reinforcement delivers ≥100 N tensile strength for reliable pulls in crowded racks.
Singlemode & Multimode SC Options
Available in singlemode (9/125µm, OS2 G.657.A1) and multimode (50/125 & 62.5/125µm, OM1–OM5). Jacket options include LSZH (default), OFNR riser (UL 1666), and OFNP plenum (UL 910) to meet diverse building code requirements.
Easy Push-Pull Operation
The SC fiber optic connector features a push-pull snap-in design similar to an RJ-45. This tool-free mechanism allows you to push to seat and pull to release-no twisting required-making high-density port access fast and reliable.
≤0.2 dB Low Insertion Loss
The ≤0.2 dB low insertion loss with precision zirconia ceramic ferrule maximizes optical signal strength and transmission quality. Supports 500+ mating cycles at ≤0.1 dB repeatability.
Designed for Indoor High-Density Fiber Installation
Engineered for high-density applications-minimizing cable waste, optimizing fiber management, and accelerating deployment for lower installation costs.

FAQ
Q: What's the difference between the UPC and APC ends on this SC fiber patch cord?
A: The APC end (green) has an 8-degree angled ferrule - return loss ≥60 dB, required by PON equipment and CATV transmitters. The UPC end (blue) has a flat dome polish at ≥50 dB (singlemode) or ≥30 dB (multimode), standard for Ethernet switches. This SC UPC to APC hybrid patch cord bridges the two interface types without conversion adapters. Green always goes to APC adapters, blue to UPC.
Q: Is this 12-core SC patch cord available in both singlemode and multimode?
A: Yes. OS2 singlemode (G.657.A1, 1310/1550 nm, up to 40 km+) and all multimode grades: OM1 (62.5/125), OM2, OM3, OM4, OM5 (50/125, 850/1300 nm). Specify fiber type when ordering; no surcharge for standard grades.
Q: Why choose a 12-fiber SC jumper cable instead of individual patch cords?
A: One 12-core cable replaces twelve separate SC fiber optic patch cords. Cable tray fill drops approximately 80%, installation is faster, and every fiber is TIA-598 color-coded for instant channel identification. In high-density ODF or data center cross-connects, the difference in management time and rack cleanliness is significant.
Q: What insertion loss should I expect from this SC fiber patch cable?
A: Specification is ≤0.2 dB (UPC) and ≤0.3 dB (APC). Most units ship around 0.12–0.15 dB for UPC, 0.15–0.18 dB for APC - every core individually tested. Test reports included at no charge on request.
Q: Can I plug an SC APC connector into a UPC port?
A: Don't. The 8-degree angle creates an air gap against a flat adapter - you'll see 2–3 dB+ loss and risk scratching both ferrules. That's what this hybrid SC patch cord prevents: each connector only meets its matching adapter type.
Q: Which cable jacket should I choose for this 12-core SC fiber cable?
A: LSZH (default) - low smoke, zero halogen, compliant with most international fire codes. OFNR - UL 1666 riser-rated for vertical runs. OFNP - UL 910 plenum-rated for air-handling spaces. PVC - general-purpose, lowest cost. All options share the same lead time.
